ELASTIC SUSPENSION FOR WHEELED eUn-oARnIAGEs.

To all whom it may concern: v

Be it known that I, EUGENE SCHNEID R, a citizen oi -the Republic of France, res ding at 42 Rue dAnjou, Paris, France, have invented new and useful Improvements in Elasticsuspension for \Vheeled Gun-Carl riages, which invention is fully set forthf in the following specification.

This invention relates to gun carriages of the known type wherein the training of the gunis effected by sliding the gun carriage body along the axle of the carriage wheels. 7

In this known type of'gun carriages illustrated in the accompanying drawings in F ig. 1 in diagrammatic vertical section alongthe axis of the axle Act the wheeled axle B-'A-*B. The carriage body 0 is slid able along the axleby means of a suitable gear comprising a pinion meshing with a rack 11 formed on' the said axle. The carriage body ca'rriestwo boxes D, DCOIltiilH- Fig. 9'is a partial cross section showing a Application filed February 28,;920., seriain 62,j11.

According to the present invention a real elastic suspension is interposed betweenthe gun carriage body C and the boxes D.

For this purpose, the boxes'D instead of fbeing fixed to thegun carriage body, may

be arranged in such a. manner as to allow a vertical sliding motion to take place between 'them and the gun carriage body.-;-

The present arrangements of boxes fixed to the'gun carriage body may also be retalned by c instructing them in such a manner that they comprise a buckle for one of the elements of a pair of leaf springs, the buckle of the other element'being carried by the block F of the support for of the corresponding roller. 1 7

Figs. 2 to 5 inclusive illustrate a constructional form designed on the last stated principles. p

In these'figures, B-A-B designates, as in the ,-diagrammatic F ig..1, the wheeled axle along the axle A of .which the gun carriage body is adapted toslidefo'r trainthe axle-pin e ing the gun. I For this purpose the axle carries a rack a over whichrolls a pinion H carried by the gun carriage, and actuated by. a suitable gear.

According to thepresent invention the boxes D which arevfixed tothe guncarriage body .C and in which are guided the blocks F carrying theaxle-pins e for thezrollers E,

comprise each a buckle D for a leaf spring I arranged transversely of the axisof the axle. This spring I is operatively connected to a leaf spring 'J'for which a buckle F is formed on the corresponding block In this manner a real elastic suspension is provided between the gun carriage body 1 C an'd'the supportingblocks of therollers E rolling.,i n'contact with'the axle A.

In each of the boxes D a's hoe L is mounted on the lower end of a screw spindle L working in a correspondingscrew-thread tapped in the box D; For firing, the shoes L are brought into contact with the'axle A (Fig. 4) .in such a manner as to prevent the suspension springs from receivingthe stresses due to the percussion. For transport, the shoes areraisedintothe position shown in Figs. 2 and 3; at the same time all shifting of the. gun carriage along the axle is prevented by means of bolts hi which are lowered into the position indicated by full lines on the left of Fig. 2. In firing these bolts are fixed in the position shown in full lines on the right of Fig. 2.

The boxes D'fthat surround the axle with their lower parts, are-formed on their inner walls with flats .03 (Figs. 3, 4 and 5) upon which are adapted to bear corresponding ribs A projecting from the axle. This arrangement providesa suitable surface for guiding thecboxes on the axle in the vertical direction 'as'well as in the horizontal direction, and affords at the same time bearing'surface of sufficient area for pulling the axle by means of the gun carriage during transport.

Fig-s6 to 13 inclusive illustrate a constructional form-of this invention wherein the rollerboxes are independent of the gun box surrounds the axle, and its lower portion is formed as a buckled for a leaf spring K, the longest leaf of which is jointed by'means of links N (Fig. 7) to axlepins 92. carried by brackets C C? on the sideplates of the gun carria -e. V

The gun carriage body. is, as shown, suspended elastically from the boxes D along which it can slide during transport; normally these boxes bear upon the axle by means of the/rollers E."

For firing, the boxes D may be fixed to the gun carriage C. For this purpose the said boxes are formed with lugs D guided during transport by screw threaded stems C carried by the side plates C of the gun carriage. Each of these stems is fitted with a nut C which can be brought into contact with the lug D so" as to form a firm conne'ction between the boxes D and the gun carriage. V r 1 4 Since the pinion H which meshes withfthe last toothed wheel of the driving transmission forsliding the gun carriage along the axle in, is carried by. the gun carriage body C, and is subjected during transport to the tively to the wheeled axle, the invention also consists in providing an apparatus for moving the said pinion out of gear, that is to say, for keeping it out of. gear with the rack a.

For this purpose the pinion H is adapted to slide along a square portion of its shaft h. It is capable of rotating in a bracket 0 formed on a screw-threaded stem 0 working in a nut p pivoted in the gun carriage body C, and fixed to a bevel pinion P. The bracket 0 is prevented from rotating by the engagement of a nib 0 (Fig. 13) in a groove formed in the gun carriage G. Rotational motion of the nut p and pinion P, intended to cause the bracket 0 to move down so as to bring the pinion 1-1 out of gear, is imparted to it by the actuation of a pinion Q fixed on a shaft 9 which is journaled in the gun carriage body C and carries an operating hand wheel p This mechanism for moving the pinion l-l into and out of gear may be operatively combined with a mechanism forbringing into and out of operation two bolts S situated opposite sockets a? formed in the axle A, and serving for locking the gun carriage to the axle during transport.

For this purpose, a tapped sleeve T guided in the gun carriage body, forms a nut for a screw-threaded portion of the shaft g. This sleeve which'receives through the operation of the hand wheel R, a movement along its axis, moves with it bymeans of two side studs 23 (Fig. 11) a forked lever U fixed on an axle S which is journaled in the gun carriage body and carries two forked levers S engaging the tails of the bolts S. The moving of the bolts out of the way is effected simultaneously with the throwing of the pinion H into gear.

The engagement of the bolts is assured by their springs, owing to the pivotal movement of the levers S towardthe axle, which movement is caused by. the disengaging movement of the pinion H.
